ORA-03206: maximum file size of (6553600) blocks in AUTOEXTEND clause is out of range

I received below error while extending the datafile. You might see below error when creating tables space too.

SQL> alter database datafile '/oradata1/ORCL/orcl101.dbf' autoextend ON maxsize 50g;
alter database datafile '/oradata1/ORCL/orcl101.dbf' autoextend ON maxsize 50g;
ERROR at line 1:
ORA-03206: maximum file size of (6553600) blocks in AUTOEXTEND clause is out of range

The reason is maximum file size for an autoenxtendable file has exceeded the maximum number of blocks allowed. Note that Oracle allows only up to 32GB datafile with 8k blocks. If you want to create a tablespace or datafile more than 32GB then you must use BIGFILE keyword.

To calicuate max datafile size:
max datafile size = db_block_size * maximum number of blocks

Solution: create a file less than 32 GB size or if you need to create datafile more than 32GB then use BIGFILE keyword.

SQL> alter database datafile '/oradata1/ORCL/orcl101.dbf' autoextend ON maxsize 32767M ;
Tablespace altered.

Hope this helps,
